I just bought a used Stihl FS 85 Trimmer, and I cannot for the life of me find out how to put trimmer line on the spool. I have hunted the entire web, including Stihl website, and cannot find out how to do this. If anyone has any information or website that shows stupid people how to do stuff, send it my way. Thanks, in advance. It is a standard head, the type that you "tap" and it feeds more trimmer line.
